Many species contain genetic lineages that are phylogenetically intermixed with those of other species. In the Sorex araneus group, previous results based on mtDNA and Y chromosome sequence data showed an incongruent position of Sorex granarius within this group. In this study, we explored the relationship between species within the S. araneus group, aiming to resolve the particular position of...

bioassays were conducted to assess the contact toxicity of two plant essential oils against adults of sitophilus granarius (l.) and tribolium confusum jacquelin du val. essential oils were extracted from seeds of carum copticum l. and cuminum cyminum l. contact toxicity was assessed by topical application and adult mortality was counted 1, 2, 6 and 24 h after exposure. bioassays were carried ou...

This study evaluated the toxicity and repellent activities of essential oils (EOs) against Sitophilus granarius (Linnaeus, 1758), both in vitro vivo conditions. The EOs obtained from Thymus pallescens No??. (Lamiaceae) Cymbopogon citratus Stapf. (Poaceae) were analyzed by GC-MS, revealed that carvacrol (56.64%) geraniol (20.8%) as respective major components. T. EO was found to be a more effect...

Substances of natural origin and more particularly essential oils currently represent an alternative solution in the fight for protection stored foodstuffs. The way to use these storage conditions remain main handicap dealing with this subject. This article develops porous supports as a medium study behavior respect insecticidal activities. process relates fixing and/or grafting clay media well...

The composition of fatty acids and insecticidal effects was performed for the Turkish mosses Dicranum scoparium, Hypnum cupressiforme, Polytrichastrum formosum, Homalothecium lutescens and the Turkish liverwort Conocephalum conicum. All structures were determined by means of gas chromatography and gas chromatography-mass spectrometry techniques. The determination of fatty acids was done using a...
